The Ameralabs TGM-7 Clear 3D Resin is a high-definition transparent photopolymer resin designed for LCD/MSLA resin 3D printers. It offers an optimal balance between rigidity and flexibility, resulting in durable parts that do not chip or break easily. With low odour and fast curing, it is a solid option for both professional workshops and semi-professional users looking for quality results with every print.

What it is used for
The TGM-7 Clear is designed for applications where transparency, detail definition and a degree of impact resistance are required. Its translucent nature makes it particularly interesting when the visual appearance of the material is part of the final result.
- Board game miniatures and collector figures with fine detail
- Transparent or translucent prototypes for interior visualisation
- Functional parts requiring moderate flexibility and impact resistance
- Display models and architectural mock-ups with a clean finish
- Parts for special effects and props requiring a glass or transparent plastic appearance
- Production of small components where the brittleness of standard rigid resins is a problem
How to use it
- Shake the resin bottle thoroughly before use, for at least 1–2 minutes, to homogenise the photoinitiator components.
- Pour the resin into your LCD/MSLA printer vat, avoiding prolonged exposure to ambient light.
- Set the exposure parameters in your slicer according to Ameralabs' recommendations for the TGM-7 and your printer's screen size.
- Start the print and monitor the first layers to ensure good adhesion to the build plate.
- Once printing is complete, carefully remove the part and eliminate any excess liquid resin.
- Wash the part in isopropyl alcohol 99.9% for 3–5 minutes, agitating or using an ultrasonic cleaner.
- Allow to dry completely before post-curing. Do not post-cure with residual liquid resin still on the surface.
- Post-cure the part under UV light (curing station or direct sunlight) until the surface is no longer tacky. Time will vary depending on the thickness of the part.
- If you intend to paint the part, lightly sand with fine-grit sandpaper (400–800) and apply primer if necessary.
Usage tips
Exposure parameters in the slicer
The TGM-7 Clear is a fast-curing resin, so it is advisable to start with exposure times at the lower end of the range and adjust progressively. Over-exposing layers of a transparent resin can cause light bleed (blooming) and loss of definition in the finest details. Consult the exposure profiles published by Ameralabs and adjust according to the actual power output of your screen.
Cleaning and post-processing
To achieve the best possible transparency, carry out a thorough wash with isopropyl alcohol 99.9% and make sure the part is completely dry before post-curing. Residual liquid resin trapped in cavities can cause staining or cloudiness in the final result. If you are looking for maximum optical clarity, a second bath in fresh alcohol noticeably improves the finish.
Storage and handling
Store the resin in its original container, tightly closed and away from light. The ideal storage temperature is between 15 and 25 °C. Always work in a well-ventilated space and wear nitrile gloves: uncured resin is irritating to the skin and sensitising with repeated exposure. Do not pour leftover resin down the drain; cure it under UV light before disposal in accordance with local regulations.
Frequently asked questions
Is it compatible with any resin printer?
The TGM-7 Clear is compatible with standard LCD/MSLA printers. Feroca distributes models such as the Phrozen Sonic MEGA 8K V2 and the Phrozen Mighty 8K, with which the TGM-7 works correctly when the appropriate exposure parameters are set. It is not compatible with FDM (filament) printers.
What is the difference between a transparent resin and an opaque resin?
Transparent resins like the TGM-7 Clear allow light to pass through the part, making them ideal for visual effects, interior visualisation or parts with a glass or translucent plastic appearance. Opaque resins (grey, white) facilitate direct painting and surface visual detail, but do not transmit light. The choice depends on the final use of the part.
Can a part printed with this resin be painted?
Yes. After full post-curing, the surface of the TGM-7 Clear is paintable. For better adhesion, it is recommended to lightly sand with fine-grit paper and apply a primer coat before painting. Bear in mind that, being transparent, the colour of the material will influence the final result if an opaque primer is not applied.
What should be used to clean parts and the vat after printing?
The recommended product for washing is isopropyl alcohol 99.9%. For the vat, remove excess resin with a silicone spatula, filter it back into the bottle if it is in good condition, and clean any remaining residue with isopropyl alcohol. Never use water to clean uncured resin.
Why are my parts coming out cloudy instead of transparent?
Cloudiness is usually caused by poorly washed liquid resin that cures on the surface, by excessive post-curing that opacifies the material, or by condensation during drying. Make sure to wash thoroughly with fresh isopropyl alcohol, dry completely before post-curing, and do not exceed the recommended UV curing time.
What is the advantage of a resin with a balance of rigidity and flexibility over a fully rigid resin?
Purely rigid resins tend to be brittle: thin parts, miniature legs or fine details can break easily. The TGM-7 Clear, by incorporating a degree of flexibility, absorbs impacts and mechanical stresses better, resulting in more durable parts for real-world use, frequent handling or transport.
Is it necessary to shake the resin before each use?
Yes. The photoinitiator components and additives in the resin can settle over time. Shaking the bottle for at least 1–2 minutes before each session ensures a homogeneous mixture and consistent results. If the resin has been stored for a long time, shake it for longer and check that no lumps or deposits have formed that will not dissolve.
Is there an alternative resin if I need a different colour?
